The size of smooth muscle cells is different in different organs but varies little within the same tissue. Great changes in cross-sectional area are observed in distended and contracted smooth muscle cells and during contraction and relaxation in neighbouring layers. Two basic types of intercellular ...
The electron micrographs obtained in this study revealed that there are two kinds of contact zones between smooth muscle cells in the rat small intestine—those with fusion of adjoining plasma membranes and those with intercellular attachments. The pattern of the former is characterized by fusion of...
SM22α is expressed exclusively in smooth muscle-containing tissues of adult animals and is one of the earliest markers of differentiated smooth muscle cells (SMCs). To examine the molecular mechanisms that regulate SMC-specific gene expression, we have isolated and structurally characterized the ...

Structure of Cardiac and Smooth Muscle Although it is striated, cardiac muscle differs from skeletal muscle in that it is highly branched with cells connected by overlapping projections of the sarcolemma called intercalated discs. These discs contain desmosomes and gap junctions. In addition, cardiac ...

Smooth muscletissue is associated with arteries and tubular organs such as the intestinal tract. This type of tissue provides weak, slow involuntary movements. Smooth musclecellsare spindle shaped with one central nucleus. Thecontractile fibersof smooth muscle cells are arranged perpendicular to each ot...
Myosin filaments are also present in smooth muscle and non-muscle cells, where they pull on actin to produce filament sliding, as in striated muscle. In vertebrates, smooth muscle and non-muscle filaments are more labile than those of striated muscle. Under in vitro relaxing conditions, dephosph...
